I think you created a pretty good plan from scratch for the most part. However, you're missing two essential exercises, especially when it comes to the ladies.
1. Squats.
2. Lunges.
For the record, you
cannot spot-reduce. Meaning, you can't pick specific exercises that exercise a specific area on your body and expect to burn off fat just from that area and nowhere else. But, you
can pick exercises which stimulate multiple muscle groups, which in turn will help reduce fat from all over the body, including her tummy area that she wants to improve. That's what makes Squats and Lunges such great exercises.
However, I am recommending doing these two exercises
only if she is physically able. If she has a debilitating bodily condition or an injuried area that worsens her condition while doing Squats or Lunges, then don't have her do them!
Remember, diet is key! She will not reduce fat from her tummy area if her diet is not clean, and forces a healthy Calorie restriction. You can find more helpful information in our Nutrition and Weight Loss section located here:

I'm sure some of the other ladies around here who have experienced having children and are able to retain their beautiful physiques are able to give some better advice.
